7x>=0
Divide by 7
X>=0 this is the domain
[0,infinity)
Answer:
225, 225 and 252 meters
Step-by-step explanation:
Let length of the 2 equal parts be each x m, then:-
2x + x + 27 = 702
3x = 702 - 27 = 675
x = 675/3
x = 225
So lengths of each parts are 225, 225, 252

Step-by-step explanation:
Answer:
Amount of money paid by each student is equal to ![\$3W+\$200](https://tex.z-dn.net/?f=%5C%243W%2B%5C%24200)
Step-by-step explanation:
Given: A group of children bought
presents that cost
each and a card that cost
.
To find: amount of money each student paid in terms of ![W](https://tex.z-dn.net/?f=W)
Solution:
Cost of each present ![=\$W](https://tex.z-dn.net/?f=%3D%5C%24W)
Cost of
presents ![=\$3W](https://tex.z-dn.net/?f=%3D%5C%243W)
Cost of a card ![=\$200](https://tex.z-dn.net/?f=%3D%5C%24200)
Therefore,
Amount of money paid by each student in terms of
= Cost of
presents + Cost of a card
![=\$3W+\$200](https://tex.z-dn.net/?f=%3D%5C%243W%2B%5C%24200)
